Case Studies in Systems Biology, 2021
The lac operon regulatory mechanism allows bacteria to sense external nutrient conditions and, accordingly, regulate gene transcription that assists in the digestion of available nutrients. The lac system produces a switch-like dynamic behavior, where the switching between ‘on’ and ‘off’ states of lac gene transcription depends on the specific ...

The ability to regulate gene expression is essential for controlling metabolic events in a cell. Proteins that function like molecular switches respond to fluctuations in the environment to maintain homeostasis. The operon model, proposed by Jacob and Monod, provides a cogent depiction for how gene expression is regulated. A molecular mechanism for the

Isolation of Pure lac Operon DNA*
Nature, 1969Two specialized transducing phages, which carry the lac operon of Escherichia coli inserted into their DNA in opposite orientations, are used as a source of complementary sequences from which to prepare pure lac operon duplex. The availability of a single pure promoter will facilitate many new experiments on genetic transcription.

Modeling Gene Expression: Lac operon
2021 43rd Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2021Gene regulation is an essential process for cell development, having a profound effect in dictating cell functions. Bacterial genes are often regulated through inducible systems like the Lac operon which plays an important role in cell metabolism. An accurate model of its regulation can reveal the dynamics of gene expression.

Hopf Bifurcation and Delay-Induced Turing Instability in a Diffusive lac Operon Model
International Journal of Bifurcation and Chaos in Applied Sciences and Engineering, 2016In this paper, we investigate the dynamics of a lac operon model with delayed feedback and diffusion effect. If the system is without delay or the delay is small, the positive equilibrium is stable so that there are no spatial patterns formed; while the ...
